Title: Data recording tape cartridge
Inventor: RIDL PETER A
IPC: G11B23/04
Filed: 2002-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a data recording tape cartridge which prevents deviation in the transverse direction of a tape reel assembly in the locked state. SOLUTION: The tape reel assembly includes a hub, a top flange and a bottom flange opposite to each other, and drive teeth. The drive teeth extend in the axial direction relative to the hub and are engaged with a tape drive chuck. A centering device holds the tape reel assembly in a centered position relative to a tape reel opening in the locked state. The centering device includes a rib and a corresponding groove. The rib is formed by one of the bottom flange and a base, and the groove is formed by the other. The groove selectively receives the rib to hold the tape reel assembly in the center position. When the data recording tape cartridge is vertically oriented, the centering device prevents the tape reel assembly from laterally shifting relative to the tape reel opening in the transverse direction.
